INTRODUCTION Tissue reperfusion following hemorrhagic shock may paradoxically cause tissue injury and organ dysfunction by mitochondrial free radical expression. Both nitrite and carbon monoxide (CO) may protect from this reperfusion injury by limiting mitochondrial free radial production. We explored the effects of very small doses of inhaled nitrite and CO on tissue injury in a porcine model ...
A one-pot synthesis of 4-nitro-3-phenylisoxazole has been carried out by treatment of cinnamyl alcohol dissolved in acetic acid with sodium nitrite; in addition, 4-phenyl-3-furoxanmethanol was obtained in 40% yield.
Hemoglobin (Hb) potently inactivates the nitric oxide (NO) radical via a dioxygenation reaction forming nitrate (NO(3)(-)). This inactivation produces endothelial dysfunction during hemolytic conditions and may contribute to the vascular complications of Hb-based blood substitutes. Hb also functions as a nitrite (NO(2)(-)) reductase, converting nitrite into NO as it deoxygenates. We hypothesize...
Some chemicals used by human such as food additives are mutagenic and mutagenicity effects analysis of them is very important because of considerable consumption by man. One of the most common methods used in the recognition of the chemicals' mutagenicity is Salmonella Typhimurium Reverse Mutation (Ames) test. The purpose of the present study is mutagenicity effects analysis of sodium nitrite, ...
We compared five methods for the determination of total and direct bilirubins in serum samples from normal controls, subjects with Gilbert's syndrome, and serum pools containing about 50 and 150 mg of total bilirubin per liter. The Kodak Ektachem method and a diazotized sulfanilic acid method with 0.15 mmol/L sodium nitrite concentrations are the only methods that gave accurate direct bilirubin...
-------------------------------------------------------ABSTRACT--------------------------------------------------The present study was to evaluate nitrite toxicity in fish gills during long-term exposure of sublethal concentration of sodium nitrite (NaNo2). The effect of nitrite on histopathological parmeters were evaluated exposing Indian freshwater fish, Cirrhinus mrigala to a sublethal conce...
